Rookie Mistake - 941 busted oil pan - Tough first day

Some of these had mild steel sumps, some were cast, what type do you have? both can be welded but knowing the material helps.

Understood.
i actually called it a day after all that...put a bucket under it and went home.
I'll tackle getting the pan off next week. thank you

Hi, Cptcrnch1.
I agree with Catsilver that both pans can be welded and I don't think pressure testing would be needed 'cos that crankcase and pan doesn't get to hold much pressure. Simple leak testing, maybe with some diesel fuel in the bottom of the pan, would probably be sufficient.

If memory serves me rightly, the belly plates on the 941s and 941Bs both bolt straight to the underside of the loader frame with 1/2" UNC bolts going into threaded lugs welded to the inside of the main frame. One of the front belly plates was usually hinged at the rear via hooks onto pieces of round bar welded to the rear belly plate. This allowed for easy dropping of this particular plate which was directly under the engine.

If you have a parts book, that should show you how they all fit together. If you are planning on making them, anything less than about 3/8" plate would likely be a waste of time and material and 1/2" would be better. You probably had a rather large part of around 12 tons sitting on top of that stump.

I don't know your part of the U.S. but, if no closer source pops up, you may find that Florin Tractors at Davis, CA., would have the pan and gasket. Hopefully, there will be a closer source. While you're in there, check that there has not been any damage to the oil pick-up.

Just my 0.02.

80H0790 - up has cast iron oil pan. Look for a used unit Part # 8S6018.
I'd be shopping the used market for belly pan/s as well. Seems front pan was standard with rear pan optional.

If in a bind and if you can get to the crack in the machine, clean it real good, grind it with a small grinder or Dremel tool with a rounded bit, then JB weld it. It should buy you time until you can find a pan or get it to a better spot to work on it. Its amazing what that stuff will fix as long as you get it real clean and follow the simple directions. I have a crack in the bottom of a cast iron power shift transmission on a log skidder that has not leaked in over ten years after using JB weld in the slightly V'd out crack. Do not use it for a structural fix however.

Thanks guys. Great info.

I'm going to try and get it welded and go from there.

I tried to get the pan down, but the oil dipstick tube attaches to the pan. It looks to be two nuts that lock together and thread into the top of the pan.
Is there a trick to getting to these two bolts. They are in a tight tight spot...cant even get on open ended wrench head to to it, much less turn it.

the only thing I can possibly see as a way, is to disconnect the dipstick tube and possibly lower the pan and then try to get those two nuts off....I'm sure there's a trick...suggestions?

also, I dont have my parts manual yet (on order)....does anyone have a part number for the gasket for the pan?
the only thing I can find for the pan installation is snapshot that shows
GMG00038 Form - Installation instructions; 139289. I cant find anything on any of these.

Pan/sump gasket only is a part # 8S1963.
